Data Collection of Analytics 
Dozzle collects anonymous user configurations using a simple beacon written in Go. Why? Dozzle is an open source project with no funding. As a result, there is no time to do user studies of Dozzle. Analytics are collected to prioritize features and fixes based on how people use Dozzle.
Where is Data Stored 
Dozzle sends anonymous data to DigitalOcean, where it is written to a flat file for processing.
Opting Out 
Dozzle analytics helps to prioritize features and spend time on the most important improvements. If you do not want to be tracked, use the --no-analytics flag or DOZZLE_NO_ANALYTICS environment variable.
